徴とする燃料噴射ポンプ。Plunger insertion hole 18 formed in pump casing 1
By reciprocating the plunger 2 within the plunger 2, the fuel within the fuel pressurizing chamber 15 formed on the top surface 2a of the plunger 2 can be fed under pressure.
An annular valve 3 configured to open and close an oil passage hole 38 formed outside the plunger 2 and spanning the top surface 2a' and the side peripheral surface 2b of the plunger 2 in the fuel chamber 14 formed in the middle portion. is inserted into the plunger 2 so as to be rotatable and slidable relative to the plunger 2, and the annular valve 3 is appropriately rotated relative to the plunger 2 using the metering operator 30 to open the oil passage hole 38 of the plunger 2. By changing the opening/closing timing of the valve, the amount of fuel to be injected can be controlled, and by displacing the annular valve 3 in the axial direction of the plunger using the advance angle controller 31, the timing of fuel injection can be controlled. A fuel injection pump characterized in that an operating element 30 and the advance angle operating element 31 are coaxially mounted on one side surface 1a side of the pump casing 1 and are overlapped with each other in the axial direction.
